Abstract

Injecteur de carburant électromagnétique (30) qui possède un corps tubulaire non magnétique (32) défini par des parois latérales, radialement intérieure et extérieure (34, 36), délimitant un espace intérieur annulaire qui contient un solénoïde tubulaire (54) et un élément annulaire de soupape (56) qui est actionné par ledit solénoïde (54) afin d'ouvrir et de fermer l'injecteur de carburant (30). La paroi radialement intérieure (34) délimite un trou central dans le corps (32), qui permet à la tige (24) d'une soupape d'admission (18) de moteur de passer à travers l'injecteur de carburant (30), ce qui donne ainsi la possibilité de monter l'injecteur de carburant (30) sur le collecteur (12) directement au-dessus de la tête de soupape (22).
